North Korea may embark on more aggressive jamming-related activities toward South Korea than in the past. North Korea has been developing a new GPS jamming device which is apparently aimed at attacking communication systems used by South Korea and between US and South Korean military forces. 

GPS jamming involves using a frequency emitting device to interfere with radio communications and can be used to jam phones, text messages, wi-fi networks and GPS systems. 

North Korea’s military has recently completed the final tests on the device and is preparing its deployment into the field.

A report by the Bureau of Weapons Review, an organization affiliated with the Ministry of the People’s Armed Forces, stated that the new jamming device can be deployed in the field, a North Korean source told Final tests of the device confirmed that the device is “stable” enough to be deployed into the field. The report also stated that the device possesses more advanced and refined attack capabilities than past devices. 

The bureau examines and determines the possibility of deploying all strategic and tactical weapons jointly developed by the country’s research institutes and military-related factories. 

The device is expected to be deployed throughout the military from next month, and North Korea may aim to quickly deploy the device within the military’s electronic warfare division and the Electronic Reconnaissance Bureau 121 (Cyber Warfare Agency) under the Reconnaissance General Bureau (RGB), which is responsible for jamming operations against South Korea.
